We're dividing 860280 by 66 
We want to divide 860280 by 66.

Going ahead to step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 66

Going ahead to step 2:
66 goes into 86 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 20 after subtracting 66 from 86.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 66

Let's proceed to step 3:
200 divided by 66 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 198 from 200 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 66

Step 4:
66 goes into 22 0 times with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
Subtracting 0 from 22 leaves us with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 66

On to step 5:
If we divide 228 by 66, we get 3 and a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 1303.0
Subtract 198 from 228 to get 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 66

Going ahead to step 6:
When dividing 300 by 66, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 13034.0
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 13034.5
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
If we divide 300 by 66, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 13034.54
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
When dividing 360 by 66, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 13034.545
Subtracting 330 from 360 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
300 divided by 66 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 13034.5454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
360 divided by 66 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 13034.54545
Subtract 330 from 360 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
The number 66 fits into 300 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 13034.545454
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
66 goes into 360 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 13034.5454545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
300 divided by 66 is 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 13034.54545454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 13034.54545454 with a remainder of 3.6e-08.
